Outer Limits 4x4 Board

Morning all, ( I did search)

I have a 92 4Runner, on 31x10.5x15 BFG M/T. I just want to know some

ideas on the pressure required in the tyres for daily driving. The previous

owner ran them at 45PSI, and given that i came from a Zook which is

around 20 seemed very high. Is this right? It is rated to 50 as a max it

says on the tyre. Also, i believe I can run them down to 20 or so before I

have issues, is this correct too.

thanks for the help.

I would say around 30-34psi depending on the ride you get

I guessed it would be lower than it presently is, as every bump more or

less tries to launch me out of the seat!

After all the 4 Runner is a 4WD, expect a roiugher ride than you get in the Family sedan. Running the pressure at 20psi you would be asking for problemie cr#p handling, increased running pressures and hence more rapid tyre wear. As stated previously somewhere around 30 to 34psi would be the ball park. Increase say another 5 psi if you doing a bit of towing or have the vehicle load with 3 kids, 2 dogs, the missus and 45 slabs of beer.

Sorry, my mistake, i meant 20PSI offroad. I have done a heap of 4WDing, it is just it has been in Suzuki's, not the larger vehicles, so I am beginning my learning curve again.

Ditto........offroad, 18 to 22 is quite OK dependent on terrain/load.

yeah on road run it at around 34+-2psi and off road 18 is fine thats what mate runs his at and it's ok 45psi there will be stuff all tread left in the middle of the tyre and like new on the outside
